Far away, at the edge of the universe, stands the Castle of the Old Skull. For millennia, the castle’s servants have maintained harmony and peace throughout the universe. But suddenly, dark forces led by the evil and cruel sorcerer Skeletor seized the castle and the peaceful planet. Standing in their way are the brave galactic hero He-Man and his friends. The decisive battle shifts to Earth, to a small California town, where a young couple, Julie and Kevin—who were accidentally drawn into the conflict—come to the aid of the forces of good.
